Auto Credit Based on Zenithspeed's Mortan System 1.4 - Beyond Insanity


NOTE: Mortan is a large and resource-intensive system. Game crashes or other performance issues are prone to occurring, especially on older or lower end devices. Lowering the game quality is reccommended.

A fictional, wacky star system composed of a multitude of planets and moons. With ten major planets, several habitable worlds, and many other celestial bodies, Mortan is something straight out of fantasy science fiction. Nearly every celestial body has its own lore and/or explanation in its description; if you are confused why something is as it is, then those will likely help. Planet to star distances are real/VB scale, but scales relative to planets are still in the 1/5th (ingame) scale.

Version 1.5 - Looking Back

This version in particular was inspired by the 1.2 version, which so far was the biggest change in Mortan's history. It was a very nostalgic era for me personally, and often look back on it. And while i can't exactly bring it back, i tried to make 1.5 sort of a "tribute" to 1.2, referencing some parts of it while also keeping it up to date with slightly increased quality. The system has been made a bit more realistic while still keeping the scifi fantasy feel it always had.


  • Fargon, moon of Vazur, replacement for Bariatus i guess
  • Naverus, shepherd moon of Ravan


  • Cyrrius: Overhauled appearance, new clouds (with cirrus clouds and storms) and better plating design
  • Merak: Decent appearance changes with new and modified structures, locations, and adjusted parameters
  • Lumina: Some appearance changes, more natural looking terrain (smudge noise), better atmosphere shader
  • Gratos: Greatly improved appearance, added thin atmosphere, moved to Arvidon orbit
  • Vazur: New filename for less bugs, completely overhauled design. Added new moon Fargon
  • Rocc: Replaced mystery ball with a memorial of it, shape and lore adjustments, new boulder spikes
  • Mortan: Medium but very noticable appearance changes, reduced size, added white "mist"
  • Ravan: Minor changes to clouds and lighting
  • Nyr: Total revamp, added research base with spawnspots, added working smoke to some volcanoes (this isn't an original technique, credits to the creator who found it out)
  • Karostus: Changed "fake water" pools to liquid oxygen to match temperature ranges in the area, alongside other changes
  • Crakliuzo: Complete overhaul, removed atmosphere, ground colors are now normal
  • Pirzer, and Exlungadus: Somewhat reduced terrain insanity, other changes
  • Mraz-Friziko-Clodno: Reworked planetary system with mild appearance and lore changes, and new orbit for Clodno
  • Ukadiron: Moved orbit outwards, new lore and mild appearance changes
  • Ampus: Textures, craters, and mild shape adjustments
  • Anubis: Increased size, tried to fix the super spiky terrain but couldn't, the insanity of the terrain is beyond rescuability


  • Removed Iskrosa+Bariatus due to a coincidental and accidental KSP Eve+Gilly resemblance
  • General orbit parameter adjustments and stuff, as usual
  • System tab now has version number marked
  • Greatly adjusted orbital inclinations of almost all celestial bodies
  • Updated liquid parameters of celestial bodies for 917 update


Most assets for terrain textures and/or rings are not made by me, and credit goes to their respective creators. I will not list them here as there are too many, and also because my memory is garbage in general to remember all of them.
If an in-game celestial body's name either resembles a, or is exactly the same as a real-life celestial body, then please take note that this is unintended and coincidental - if any name may have an offensive meaning, please tell me and i will rename it later unless the celestial body is a crucial part of the planetary system.

    i'm not completely sure, but i think it may be something to do with the "noise" section of the planet builder having too high of a number in one of its areas such as the strength or frequency, the game's planet editor typically does not like very large numbers

    我不是英语使用者,但我上传复杂地形的星球时经常失败,然后他会弹出一个窗口,上面写着characters in path

    I am not an English user, but I often fail to upload planets with complex terrain, and then he will pop up a window with characters in path

    can you please explain "illegal characters in path"?
    if you are a non-english speaker and are using a translator, try to use different words in your language with similar meaning; i would help solve your issue but i currently cannot completely understand your message
